Ethnic differences in affect intensity, emotion judgments, display rule attitudes, and self-reported emotional expression in an American sample

Abstract: Research of the past two decades has shown that cultures exert considerable influence over emotion. Most, if not all, of the cross-cultural research reported to date have been on samples obtained in different countries. Although it is important to address questions of cross-cultural similarities and differences via the testing of between-country differences, we need to be concerned with possible cultural differenceswithin countries as well. The assessment of cultural differences within countries would have implications for not only our conceptual understanding of cultural influences on emotion, but also our empirical methods and procedures. In this study, American subjects were self-classified into one of four ethnic groups, and provided us with data concerning affect intensity, display rule attitudes, self-reported emotional expression, emotion labeling, and intensity ratings. The results indicated considerable differences in emotion judgments, display rules, and self-reported emotional expressions as a function of ethnicity within an American sample. The differences are discussed in terms of the need to search for psychologically meaningful and relevant definitions of culture which would cut across ethnicity or country.

Quantitative Trait Loci for Murine Growth

Abstract: Body size is an archetypal quantitative trait with variation due to the segregation of many gene loci, each of relatively minor effect, and the environment. We examine the effects of quantitative trait loci (QTLs) on age-specific body weights and growth in the F2 intercross of the LG/J and SM/J strains of inbred mice. Weekly weights (1-10 wk) and 75 microsatellite genotypes were obtained for 535 mice. Interval mapping was used to locate and measure the genotypic effects of QTLs on body weight and growth. QTL effects were detected on 16 of the 19 autosomes with several chromosomes carrying more than one QTL. The number of QTLs for age-specific weights varied from seven at 1 week to 17 at 10 wk. The QTLs were each of relatively minor, subequal effect. QTLs affecting early and late growth were generally distinct, mapping to different chromosomal locations indicating separate genetic and physiological systems for early and later murine growth.

Database of diazotrophs in global ocean: abundance, biomass and nitrogen fixation rates

Abstract: . Marine N2 fixing microorganisms, termed diazotrophs, are a key functional group in marine pelagic ecosystems. The biological fixation of dinitrogen (N2) to bioavailable nitrogen provides an important new source of nitrogen for pelagic marine ecosystems and influences primary productivity and organic matter export to the deep ocean. As one of a series of efforts to collect biomass and rates specific to different phytoplankton functional groups, we have constructed a database on diazotrophic organisms in the global pelagic upper ocean by compiling about 12 000 direct field measurements of cyanobacterial diazotroph abundances (based on microscopic cell counts or qPCR assays targeting the nifH genes) and N2 fixation rates. Biomass conversion factors are estimated based on cell sizes to convert abundance data to diazotrophic biomass. The database is limited spatially, lacking large regions of the ocean especially in the Indian Ocean. The data are approximately log-normal distributed, and large variances exist in most sub-databases with non-zero values differing 5 to 8 orders of magnitude. Reporting the geometric mean and the range of one geometric standard error below and above the geometric mean, the pelagic N2 fixation rate in the global ocean is estimated to be 62 (52–73) Tg N yr−1 and the pelagic diazotrophic biomass in the global ocean is estimated to be 2.1 (1.4–3.1) Tg C from cell counts and to 89 (43–150) Tg C from nifH-based abundances. Reporting the arithmetic mean and one standard error instead, these three global estimates are 140 p 9.2 Tg N yr−1, 18 p 1.8 Tg C and 590 p 70 Tg C, respectively. Uncertainties related to biomass conversion factors can change the estimate of geometric mean pelagic diazotrophic biomass in the global ocean by about p70%. It was recently established that the most commonly applied method used to measure N2 fixation has underestimated the true rates. As a result, one can expect that future rate measurements will shift the mean N2 fixation rate upward and may result in significantly higher estimates for the global N2 fixation. The evolving database can nevertheless be used to study spatial and temporal distributions and variations of marine N2 fixation, to validate geochemical estimates and to parameterize and validate biogeochemical models, keeping in mind that future rate measurements may rise in the future. The database is stored in PANGAEA ( doi:10.1594/PANGAEA.774851 ).

Toward a Theory of Sustainability Management: Uncovering and Integrating the Nearly Obvious

Abstract: The continuing evolution and increasing salience of the concept and practice of sustainability among individuals, organizations, and societies worldwide appears to warrant the development of conceptual approaches to theories of sustainability management for application to management research, education, and practice While other management theories have been employed by many management scholars to help explain the need for and advancement of sustainability management, none of those theories appear to have the unique features, benefits, opportunities, challenges, or orientations to assist individuals, organizations, and societies to move toward sustainability as much and as soon as appears necessary However, since the consideration of theories of sustainability management is relatively new for most management scholars, the authors hope this article begins a dialogue among those stakeholders to better describe, develop, and apply this and related theories of sustainability management as significantly, effe
